Ravenous

A Navy Petty Officer is suspected to have been eaten by a bear after a group of teenagers found his dog tags in bear feces in a national forest. However, autopsy reveals that the Petty Officer was killed by a blade before his corpse was eaten by a bear. Evidence also shows that he was camping with a woman, who is now missing. The team's search for the woman and the Petty Officer's killer leads them to a realization that their case may be linked to several women of similar appearance who have been found dead in the national forest which leads Gibbs to suspect that someone's using the park deaths to disguise the fact that they're actually committing murder.
